OVERVIEWSport Scale is a somewhat “relaxed” version of the Scale event. In Sport Scale, dimensional accuracy is based on visual assessment of similarity of outline instead of direct measurement of dimensions. This can help speed static judging, thereby making Sport Scale a feasible event even at smaller contests. In addition, the data documentation package is simplified by not needing a dimensioned drawing. This expands the number of prototypes that can be modeled.

For the full rules for this event, please see the Sport Scale rules in the NAR Pink Book.

SCORINGThe score is the total of the Static Judging score and the Flight score. In summary:

Similarity of Outline: 200 points

Finish, Color, and Markings: 200 points

Degree of Difficulty: 100 points

Craftsmanship: 300 points

Flight and Mission Points: 300 points

Highest score wins.

Data Package. A data package is required that documents the appearance (outline, colors, markings, etc.) of the prototype. Dimensioned drawings can be provided if desired but are not required.

Size. Sport Scale has three subclasses based on the size of the model:

Sport Scale. Any model size is acceptable.

Peanut Sport Scale. The model must be no more than 30 centimeters in overall length or no more than 2 centimeters in body diameter.

Giant Sport Scale. The model must be at least 100 centimeters in overall length or at least 10 centimeters in body diamete

Each category has interesting challenges and benefits. Giant Sport Scale is especially crowd pleasing due to the large size of the models (and often the large motors used by the large models).

Judging Distance. Similarity of Outline is judged at a distance of one meter. At this distance, the proportion of length, diameter, fin size, and other features are evaluated. After judging Similarity of Outline, judges may closely approach the model to inspect craftsmanship, paint texture, and other features. Therefore, you need to build a nice model.

Note that Sport Scale is not “one meter scale.” A model that looks OK at a distance of one meter but looks poor up close will probably not get a high score. For example, erratic glue joints might not be highly visible from a distance but will be seen when judging for Craftsmanship points.

Scale Modeling Techniques. The scale model aspects of Sport Scale are essentially the same of as for the Scale event. See the Scale event page for further information.
